Exploration Potential

Potential for significant increases to both stratabound and vein type mineralization exists throughout the property. Drilling in Zone 3 has so far been restricted by topography and drilling depth. The furthest hole to the north on the mineral resource (hole PC-95-125) intercepted identical vein type mineralization in the same stratigraphic/structural setting as seen in the underground workings, indicating the vein is still open-ended and continuing to the north. Confirmation of the continuation of the MQV was demonstrated with the deep drilling program at Casket Creek where drillhole PC-11-187w2 intersected MQV-like material at the approximate projected location. Furthermore, the trend of the known MQV vein directly intersects the Rico Showing, where a similar vein type occurrence has been exposed at surface in bedrock four kilometres north of the last drill hole. This zone also has excellent potential for hosting further stratabound type mineralization.

The southern part of the property contains numerous exposures of vein type material in identical geological settings to that found in the Main Zone. Some wide spaced exploration drill holes have also returned stratabound type mineralization over three kilometres south of the defined mineral resource. These mineral showings ("Zones") are approximately 1 kilometre apart and extend approximately 10 kilometres to the south from the Main Zone 3 (at the mine site) to Zone 12. Associated stratabound mineralization has the potential to significantly increase the throughput of the mill, due to its much higher tonnes per vertical meter of depth.
